It will be apparent that forproper operation these gears must mesh laccurately and by this structureis provided means whereby the accurate meshing of these gears may beobtained.

On the outer end of the upper frame II is a permanent pivot bracket 28attached to the upper frame II. To this pivot bracket is attached aconventional toggle lever reset mechanism consisting of the lever 29 andthe toggle 30. This toggle lever mechanism is more or less conventionaland will not be discussed in detail except to point out that the pivotalpoint 33 is slightly inward of the line of the pivot points 3| and 32which provides a locked toggle lever which will hold the outer end ofthe frame II securely in place as long as these'pivot points retaintheir locked position. However, as will later be explained, upon releaseof the release mechanism on the inner end, the pivot point 3| movesslightly outward and this has the effect of changing the pivot points tounlocked position, whereupon the outer end of the frame I I may moveupward.

Mounted on the sides of the upper frame I I are push release bars 34.These bars are mounted with lever extensions 35 and 36 extending throughthe bottom of the upper' frame and are sprung upward against .the topframe II by torsion springs 35'. The inner end of the push bar levers 36abut upwardly against the end of the latch release lever 38 on the shelfextension 81. By referring to Fig. 6, the structure of this latchrelease lever will be clearly understood. The lever is pivoted on thepivot pin 39 which is mounted in ears 39 of the sub-frame 40 which isclearly shown in Fig. 4. YAround the pin 39 is a torsion spring 4I whichurges the release lever 38 to counter-clockwise rotation around thepivot pin 39. On the end of the latch release lever 38 is a lip 38 whichnormally abuts against the upper edge of the latch 4I, holding it inlocked relation to the pin 45, permanently aixed in the `wringer head,by means oi the bent shoulder By referring to Fig. 6, the constructionof this latch will be well understood. 'I'he inwardly bent ears haveholes 42' through which the pin 42 extends, and one of the ears has aboss 44 and a ledge 44' which cooperate with the pierced ear 44" in thesub-frame 40 to hold the latch in operative relationship with therelease latch lever 38. The operation of this latch and release leverwill be well understood when it is appreciated that when the safetyrelease 34 is pressed downward, the fulcrum levers 36 abutting againstthe shelf end of the release lever 38 force this release lever intoclockwise rotation. This depresses the lip 38 under the top edge of thelatch 43 and permits the latch 4| to rotate counter-clockwise and thusreleasing the shoulder 45' from under the pin 45, which releases theupper frame II on its inner end whereupon the spring 38 forces the rollsupward which permits the top frame II to take the position shown in Fig.3.

By carefully considering Fig. 3, it will be appreciated that thismovement results in rotation of the toggle lever pivot point inwardwhich has the effect of unlocking the toggle whereupon the outer end ofthe frame may also move upward. This action is further assisted by thenatural resultant shock and the combination of these two elementseffectively results in the release of the outer end of the upper frameII. l

The upper frame II is prevented from separating from the lower frame byslotted straps 49 and 5S, the strap 49 being fastened to the upper frameby the pin 60 and to the lcwer frame by the pin 6| thru the slottedopening 52. The outer straps 53 are attached by the pin 54 in the upperframe II and the pin 55 in the lower frame I8 through the slot 55'.

It will be appreciated that it is necessary to provide means whereby thespur gears I6 and I1 are held in proper mesh. This is done by means ofthe adjustment screw 21 in the boss 46 permanently riveted in thesub-frame 46 through the hole 46'. It will be appreciated that thesegears may be moved apart by moving the screws upward and tighter meshmay be obtained by adjustment downward. lThe vscrew 21 is held in properadjusted position by a friction spring 41 around the adjustment screw21, as shown.

When the top frame is again assembled on the lower frame, properalignment of the frames is assisted by the cross pin 66 entering intothe slot 48' in the extension 48 of the lower frame.

This will be well understood by referring to Fig. 3.

The wringer head I4 and the sub-frame 46 are mounted in a conventionalmanner in the lower frame I6 and the upper frame II, respectively. Thedetails of these mountings are clearly shown in the drawings and willnot be described in detail.

From the foregoing description itwill be well understood that a wringerhead structure is provided which assembles the wringer and wringer headin a unified structure with the top frame extending practically over theentire device. This is a decided improvement in appearance over formerstructures wherein the wringer was a unit attached to a wringer head asa unit. Moreover, in a structure of this character there is provided aneffective push bar safety release, a pressure reset mechanism and a rollstop.

Now referring to Figs. 8 and 9, I show a modiflcation wherein the safetyrelease bars 34 are eliminated and in their stead on the head end of thewringer is mounted a safety ball 51 which has a stem 51 and a washerv 58which contacts the latch release lever through the hole 59. By comparingFig. 9 with Fig. 5, it will be readily appreciated that the releaselever 60 is the same as release lever 38 except that the outer end hasbeen cut oi. It will be appreciated that any downward or tiltingmovement of the ball 56 will result in the washer 58 depressing the lip6| and releasing the latch 4|. Thus I provide a wringer made up ofpractically the same parts but of considerably different appearancebecause the release bars 34 have been omitted and the safety ball 56added. The operation of the wringers is, of course, the same in bothcases.
